1995

1995 (MCMXCV) was a common year starting on Sunday (dominical letter A) of the Gregorian calendar, the 1995th year of the Common Era (CE) and Anno Domini (AD) designations, the 995th year of the 2nd millennium, the 95th year of the 20th century, and the 6th year of the 1990s decade.

This was the year that the Internet entered public consciousness and also the year it was completely privatized and the United States Government no longer funded it with public money - in April 1995 the NSFNET was retired.America Online and Prodigy offered access to the World Wide Web system for the first time this year, releasing browsers that made it easily accessible to the general public.

Randomness

Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over a large number of events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy.

The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. Random variables can appear in random sequences. A random process is a sequence of random variables whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory and the various applications of randomness.
